Accumulated precipitation this winter through the end of
February, from northern Iowa into the southern two-thirds of
Minnesota and westward to the Dakotas, ranged from 125 percent of
normal to well over 200 percent, meteorologists say.

That raises the risk of major flooding, especially in the big
corn, spring wheat and soybean areas of North Dakota's Red River
Valley and the upper Mississippi River region

Illinois and Iowa alone produce almost a third of corn and
soybeans in the United States, the world's leading exporter of
those industrial crops. North Dakota and Minnesota produce more
than half of U.S. spring wheat and durum, the highest protein
wheats.

While U.S. crops in the north are under threat of floods, down
further south, it's
droughts that have damaged production.
